Thinking about getting a USB oscilloscope for basic DIY automotive use and learning. 2 channels seems like it would be enough, but I don't know about the other specs. The PicoScope 2204A are around the £100 mark https://www.picotech.com/oscilloscope/2000/picoscope-2000-specifications, however picoscope say that it is no use for automotive - but they are presumably talking professional use. Picoscope suggest the 4225,https://www.picoauto.com/products/automotive-oscilloscope-kit/picoscope-4000-series-specifications but at around the £700 mark that's not happening. Don't want to be interrogating the CAN bus or anything just back testing sensors, compression test etc. Their Automotive specific software only works on the more expensive models but unsure as to how important that is.
